Windows 10: is there a way to delete every x number of files via CMD or powershell

in a folder I have 300 files (in my case its over 25k).

I wish to delete every 20, or every 30 files, or every set pattern of files, how can this be done?

things i've tried, using a few selection tool to select every set number of files so I can delete but none has worked on simple ones such as every 20 or every 30 files.

please help!

Only write one number to log file and delete old ones?

Hey,

I'm trying to have some software read from a .text file a number (GPU Temp) but the software will only the first number in a list (Or the first anything)

Is there a way to have to log file delete the previous entries and write the new number in it's place without any headers?


EDIT:

Sorry I'll try again.

I have some webcam software that can read a number (or whatever) from a text file and then it displays the number as an overlay.

See here: http://10.244.193.13:8081/

I was trying to use GPU-z to do this but as it logs as a list the webcam software can't update properly (also it reads the headings of the file and displays them instead)

Is there anyway to alter the logging to only output just the number (GPU Temp) and to delete the old numbers so the new value is the only value in the file.

 

Instructions for deleting files, using CMD

Hello to the Community,

Need to delete lots of files; some are large.

I'm looking for the steps to permanently delete selected files, using CMD (I am NOT a skilled User)

The standard Delete via File Explorer sometimes doens't work....and/or is very slow to delete.

Its 2-step operation... to collect, and then delete via the Recycle Bin .... takes
approximately forever on some files.

Google research shows me there's some simple ways to use CMD like DEL / RMDIR / /Q /S But I don't know how to use them.

Could someone send me the specific steps I should enter?

And also, what is the exact layout/format for defining the file(s) to be deleted, in each CMD string ?

Thank you,

Gary
